[Gluster-users] Gluster - Performance issue while copying bulk files/folders

[Srikanth Mampilakal]

The performance when copying or testing using dd command is very fast and
70 mb file take less than 3 min to copy to the Storage Volume.

Its a ISCSI based Storage presented to the clients

Thanks
Sriikanth
